The sum of the numbers in column “Value when activated” when all INx (where 1≤x≤16) are
active that is=1; is 65535. 65535 is the highest boolean value that can be converted to an
integer by the IB16 function block.

13.10.2 Application
GUID-221AFC68-C31C-459F-8301-2A8048CB93CE v1
Integer to Boolean conversion for six-zone busbar BCTZCONN is used to transform the zone
connection integer signal of each CT from one bay function block into 7 binary (logical) signals
in the six-zone busbar differential protection. It is intended to facilitate the recording of zone
connection information from each bay function block to the disturbance recorder.
The BCTZCONN function does not have a logical node mapping and is designed to receive only
an integer input locally. If the BLOCK input is activated, it freezes the logical outputs at the last
values.
More specifically, it transfers an integer input ZONCONI to a combination of activated binary
outputs ZONEx (1≤x≤6) and CZ, so that:

logical value
